What is the pH range of a neutral solution?

A neutral solution is defined as one where the concentration of hydrogen ions (H⁺) is equal to the concentration of hydroxide ions (OH⁻). In water at 25°C (room temperature), this occurs at a pH of 7. At this pH level, the solution is neither acidic (pH less than 7) nor basic (pH greater than 7).

The pH scale ranges from 0 to 14, with values below 7 indicating acidity, values equal to 7 indicating neutrality, and values above 7 indicating basicity. In practical terms, a pH of 7 signifies that the solution contains equal amounts of H⁺ and OH⁻ ions, which is characteristic of pure water and many aqueous solutions under standard conditions.

Other options present pH values that either indicate mild acidity (like 5 or 6) or mild basicity (like 8), but these do not reflect a neutral state. Therefore, the only correct answer that accurately describes the pH of a neutral solution is 7.
